SAMUEL S. FBETZ, OF PHILADELPHIA, PENNSYLVANIA.

UMBRELLA Am) PARASOL.

Specification of Letters Patent.

Patented Apr. 2, 1918.

Application filed December as, 1917. ser al No. 209,207.

To all whom it may concern:

Be it known that I, SAMUEL S. Fnnrz, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Umbrella and Parasol, of which the following is a specification.

My invention relates to an improvement in an umbrella and parasol, and it consists of means for reinforcing the portions of the metallic ribs thereof whereby they are vastly strengthened, and their life is increased, the umbrella or parasol is not liable to be'blowninside-out, and less material is required for the skirt or cover of the umbrella or parasol, other portions of the ribs being left in comparatively normal condition whereby their elasticity is preserved, and the portion of the cover of the umbrella thereon is adapted to bend said portions and to assume a shape proper in umbrellas and parasols.

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specific details shown and described, as long as they are within the spirit or scope of the claims.

Figure 1 represents a side elevation of a portion of an umbrella embodying my invention.

Fig. 2 represents a longitudinal section of one of the ribs thereof on an enlarged scale, on line 22 Fig. 3.

Fig. 3 represents a transverse section on line 3-3 Fig. 2.

Figs. 4, 6, and 7 and 8 represent transverse sections of modifications.

Fig. 5 represents a section similar to Fig. 3 in inverted position.

Fig. 9 represents a side elevation of a portion of an umbrella showing another modification.

Fig. 10 represents a side elevation of the frame of the umbrella in folded condition.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings.

1 designates the rib of an umbrella which is longitudinally channeled and U-shape, and connected pivotally with the notched collar'2 on the stick 3, and with the stretcher 4, the latter being pivotally connected with the runner 5 of the umbrella, which features are well known in the art.

In the channel 6 of the rib is fitted the U-shaped member 7 which is adapted to reinforce the rib, and it may be a metallic rib of reduced thickness placed in inverted position on the rib, as in Figs. 2, 3, 5 and 6, or it may be nested in the rib as in Fig. 4, or composed of a member 8 of round metal as in Fig. 7, or a member 9 of metal quadrilateral in cross section, as in Fig. 8.

In order to retain the member in position, I may employ the collars 10 which clasp or embrace the rib and exterior portions of said member and so retain either member tightly with its rib, or the said member may be held in the rib as in Fig. 10 by pinching in the terminals of the legs of the U-shaped rib as at intervals so as to be compressed against the contiguous sides of the reinforcing member, as at 11, Fig. 9.

It will be seen that the rib is vastly strengthened and rendered more durable by the inclosure of the reinforcing member therein, in the portion thereof between the notched collar and place of joint connection of the stretcher, and said portion is so stifiened that it will resist the action of drafts of air from within the umbrella so as to prevent the latter from being blown inside out, said portion being furthermore left in right lined condition whereby it will take less quantity of material for the cover or skirt from the stick to the tips of the ribs since the curvature of said cover or skirt is reduced, hence there is a saving of material in making the cover or skirt. The portions of the ribs from the joint connections with the stretchers to the tips are left in normal condition whereby their elasticity is preserved, and they are adapted to be bent by the cover so that'the portion of the latter thereon will assume a partial hemispherical shape proper in an umbrella or a parasol.

Again the umbrella will fold in thin condition as shown in Fig. 10.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

1. A rib of an umbrella or parasol composed of a reinforced portion extending from the stick connection joint to the stretcher connection joint, and another portion in a normal resilient condition extending from the latter named connection joint to the tip of the rib.

2. A rib of an umbrella or parasol of channeled form having in the channel thereof from the stick connection joint to the.

stretcher connection joint a reinforcing member, and havmg the remainder of the rib from the latter named connection oint to the tip of the rib in normally resilient.

condition.

3. A rib of an umbrella or parasol of channeled form having in the channel thereof from the stick connection joint to the stretcher connection joint a reinforcing member and having the remainder of the 10 rib from the latter named connection joint to the tipof the rib in normally resilient condition, and means for retaining said reinforcing member in the rib.
